In India, which airport ranked first in a national Customer Satisfaction Index Survey that compared the experience of passengers at different airports?

Introduction / Context:
This question relates to the quality of infrastructure and passenger experience at Indian airports. Airport authorities periodically conduct Customer Satisfaction Index or similar surveys to rate airports based on cleanliness, services, staff behaviour and overall comfort. Knowing which airport secured the top rank in such a survey shows awareness of developments in Indian civil aviation and regional facilities beyond the largest metro cities.

Given Data / Assumptions:
- The question refers to a Customer Satisfaction Index Survey for airports in India.
- It asks which airport ranked first in that survey.
- Options include Udaipur, Raipur, Amritsar, Dehradun and Jaipur airports.
- We assume this relates to a widely reported survey in which a relatively smaller airport performed very well.

Concept / Approach:
The concept is straightforward factual recall, but clever test takers can also use pattern recognition. Often, surveys highlight airports that are not the busiest but are very well managed. Regional airports that are easier to maintain sometimes outscore crowded metro hubs in satisfaction ratings. Among the options, Raipur Airport gained attention for achieving the highest satisfaction scores among Indian airports in such a survey.

Step-by-Step Solution:
Step 1: Recall news items about a central India airport being rated highest in customer satisfaction by an official survey. Step 2: Identify this airport as Raipur Airport, also known as Swami Vivekananda Airport in Chhattisgarh. Step 3: Compare this with Udaipur, Amritsar, Dehradun and Jaipur, which are important but were not highlighted as topping the national satisfaction index at that time. Step 4: Link the recognition to efforts made at Raipur in terms of cleanliness, staff courtesy and efficient operations. Step 5: Conclude that Raipur Airport is the correct answer.

Verification / Alternative check:
As a cross check, remember that the Airports Authority of India often announces awards where Raipur Airport features prominently for both customer satisfaction and cleanliness. Recalling such awards strengthens your confidence that Raipur, and not the tourism centric airports like Udaipur or Jaipur, topped this specific survey. Cross checking this pattern ensures that the answer is not a guess based only on city popularity.

Why Other Options Are Wrong:
Udaipur Airport serves a major tourist destination but did not hold the top rank in the referenced satisfaction survey.
Amritsar Airport is important due to religious tourism but was not reported as number one in that particular index.
Dehradun Airport serves the hill region and pilgrims but has not been widely reported as topping the all India satisfaction chart.
Jaipur Airport is a major airport in Rajasthan but again did not achieve the highest national satisfaction score in the survey mentioned.

Common Pitfalls:
Many students assume that tourist heavy cities such as Udaipur or Jaipur must have the best airports and choose them without recalling the actual survey result. Another mistake is to think only of metro airports, even when they are not among the options, and then randomly pick any remaining choice. A better strategy is to memorise a few key award winners each year, especially when the winner is a less obvious city like Raipur, because such surprises often become exam questions.

Final Answer:
The airport that ranked first in the Customer Satisfaction Index Survey in India was Raipur Airport.
